Bloomberg: Comcast’s NBCUniversal expects to exceed $1 billion in advertising sales with the Summer Olympics in Rio de Janeiro next August. Commitments from sponsors including Nike, Procter & Gamble, Kellogg and Coca-Cola are on pace to top the 2012 London games, according to Seth Winter, EVP of sales at NBC Sports. “What we’ve seen so far indicates that people are very, very excited about the Rio games,” Winter said. Live sporting events are among the bright spots in an increasingly fragmented media landscape.
